3 CUCM 8.x SOFTWARE RELEASE STATUS 3

4 Release Status for CUCM 8.x 8.0(1) Feb (2c) May (3) July 2010 Several subsequent releases Latest is 8.0(3a)SU2 March (1) Nov 2010 Latest is 8.5(1)SU1 Feb 2011 UC 8.6 Beta Trial Various UC products including CUCM In progress 4

5 CUCM 8.x NEW FEATURES / ENHANCEMENTS 5

6 Cross-Cluster Extension Mobility EM traditionally limited to intra-cluster users/devices Customers may have more than one CUCM cluster Want to have the same features and services no matter where they log in Technical challenges Cross-cluster functionality Security Call Routing 6

7 Cross-Cluster Extension Mobility Registration Process High-Level Home vs. Visiting cluster Relative to the EM user Login to phone on Visiting cluster Home cluster receives device information and builds temporary device profile Home cluster TFTP builds configuration file After login, Visiting cluster directs phone to Home cluster TFTP server to download configuration Phone cross-registers with Home cluster 7

8 Cross-Cluster Extension Mobility 8

9 Cross-Cluster Extension Mobility Configuration Basic EM configuration Service activation, phone service, profiles, etc. EMCC configuration Need to specify a common SFTP server that all clusters can access Service Parameters Cluster ID, CSS settings, etc. Enhanced Mobility and Unified Communications 9

10 Intercompany Media Engine (IME) Enhance B2B communications Interconnect with other companies via the Internet using SIP trunks IME moves calls from the PSTN to the Internet Join IME network and CUCM enrolls DIDs IME servers publish DIDs to IME network First call to an enrolled DID is placed via the PSTN Routes are learned so that subsequent calls to an enrolled DID are routed as IME SIP calls 10

11 Intercompany Media Engine (IME) 11

12 Intercompany Media Engine (IME) Components CUCM 8.0 Enrolls DIDs to IME server Updates IME routes sent from IME server IME Server Participates in IME network Publishes DIDs IME routing validation Sends learned routes (SIP) to CUCM 12

13 Intercompany Media Engine (IME) Components ASA 500 Signaling and media security Blocks unauthorized calls Enrollment Server Hosted by GoDaddy CA for IME servers 13

14 Service Advertisement Framework (SAF) Reduce complexity of large voice deployments No full-mesh configurations Dynamic sharing of call routing data 2 major components Service Advertisement Framework (SAF) Network protocol modeled after EIGRP to enable sharing of call routing data Call Control Discovery (CCD) Client-side service that advertises/requests call routing data to/from SAF networks Devices running CCD are SAF Clients 14

15 Service Advertisement Framework (SAF) Hosted DN ranges are advertised to the SAF network Call Agents subscribe to Hosted DN service and learn routes from SAF network! 15

16 Service Advertisement Framework (SAF) Configuration Components SAF Forwarder Shares call routing data between SAF clients and amongst neighbors Maintains call routing DB Configured in IOS SAF Client Runs CCD services External clients vs. Internal clients Configured in CUCM 16

17 Virtualization Introduced in 8.0 Supported with UC on UCS Mixed install support for clustering Clustering Prefer HW redundancy Server roles should factor into redundant design 8.5 brings new overlays and HW support Added support for B-Series configurations as well as updated C200/C210 M2 configurations 17

18 TFTP-HTTP TFTP server hosts files for devices Previously, TFTP UDP port 69 only Now supported via HTTP TCP port 6970 Endpoints will prefer HTTP over TFTP Currently, 89XX/99XX phones only Benefits of TFTP-HTTP QoS classification (TFTP = Scavenger) Smaller payloads (1500 vs. 500 bytes) Connection-oriented Speed improvements on WAN and LAN 18

19 DST and Time Zone Changes DST changes often come as a surprise Regardless of purpose, changes can be problematic Previously, updating DST and Time Zone required installation of CUCM release and firmware updates Time Zone definition removed from CUCM DB DST and Time Zone Updates now done at OS Post 8.x, install a single COP file Changes are automatically picked up by the DB, RTMT, and phones Ease of administration 19

20 LDAP Enhancements Support creating custom LDAP filters via CUCM Admin interface Formerly only done via AXL or SQL DB See Bill Bell s blog on AXL SQL Toolkit Now done directly within GUI System > LDAP > LDAP Custom Filter Previously modified default filters become Custom Filter Updated LDAP integration support 20

21 CODEC Support and Selection Continue to update CODEC support Internet-based CODEC Internet Speech Audio CODEC (isac) Device-specific support 8961, 9951, 9971 Region Configuration updates Audio CODEC renamed to Max Audio Bit Rate Video Call Bandwidth renamed to Max Video Call Bit Rate (Includes Audio) Audio CODEC Selection Logic CUCM now prefers BEST sounding CODEC as opposed to higher bit rate vs. lower bit rate 21

22 SIP Trunk Early Offer Previously required MTP for Early Offer on SIP Trunk SIP Trunk can be configured to provide Early Offer for outgoing voice/video calls Default is delayed offer Checkbox on SIP Profile Only applies to SIP trunks No change to CUCM line side signaling» SIP phones use delayed offer May still need an MTP in some cases Ex: CODEC mismatch Ties into increased focus on video and interoperability 22

23 Video Interoperability Emphasis on video continues to increase Official support and testing of interoperability between CUCM and 3rd-party video endpoints using SIP CUCM unable to pick the right payload for optimal resolution OR may simply not provide video due to incompatibility in payloads Treat all SIP endpoints using the standard SIP protocols Support High Definition (HD, 720/1080p) negotiation between UC endpoints and 3 rd -party in H.264 CODEC Wide scope of interoperability testing UC, CTS, 3 rd -party, etc. 23

24 Mobility Enhancements Feature updates for CUCM-based mobility e.g., Mobile Connect Unified Mobile Communicator (CUMC) clients now register directly with CUCM Goodbye, Unified Mobile Advantage (CUMA) Increased focus on Mobility client(s) Ex: Cisco Mobile for iphone 24

25 CTI Scalability Improvements Increased CTI Scalability per server 7825 " 900/subscriber vs " 1000/subscriber vs " 3375/subscriber vs Cluster limitations increased accordingly Single server limit x 4 = Cluster Total 4 = Max # of Active Subscribers in Cluster 25

26 MGCP FXO Caller ID Previously, no Caller ID information such as party number or name reported Required H.323 Enabled via checkbox on gateway port in CUCM Enable Caller ID Ability to globalize numbers 26

27 CUCM 8.x UPGRADE PATH(S) 27

28 Upgrade Path(s) to CUCM

29 CUCM 8.x KEY TAKEAWAYS 29

30 Virtualization Key addition for UC 8.x Key Takeaways Overall, CUCM 8.x brings lots of administrative-facing features Cross-Cluster EM is now possible IME and SAF are intriguing TFTP-HTTP development could provide additional benefits with further development Focus on Video and Mobility continues to increase 30
